Top Tips for Tankless Water Heater Maintenance

With hard water being a common issue for tankless water heaters, it’s crucial for homeowners to understand its maintenance needs and prevent premature wear. In today’s post, we’ll delve into top tips for maintaining your tankless water heater.

Regular Descaling

The primary maintenance task for any tankless water heater is descaling. It involves removing mineral deposits from the heater’s interior components, which, if left unchecked, can hinder its efficiency and longevity. It is recommended that households with hard water should descale their tankless water heaters annually. However, for those with softer water or using a water softening system, the frequency can be reduced to once every three to five years.

Flushing Your Tankless Water Heater

Tankless models also require flushing, although less frequently than their tanked counterparts. This process involves running a cleaning solution, such as vinegar, through the heater to clean out any sediment or scale buildup. Typically, a tankless water heater should be flushed every two to three years. However, this may depend on water usage and water hardness. Keep an eye out for system error codes or signs that flushing is necessary, such as a decrease in water pressure or efficiency.

Regular Inspections and Cleanings

In addition to descaling and flushing, regular inspections and cleaning of accessible parts can play a significant role in maintaining your tankless water heater. This includes checking and cleaning the in-line water filter, which captures debris before it enters your unit, and ensuring the air filter is clear of dust and debris. 

Professional Help vs. DIY Maintenance

While many aspects of tankless water heater maintenance can be handled by homeowners, there is much better value in consulting with or hiring a licensed plumber for more complex tasks. A professional can ensure that all maintenance is carried out correctly and safely, and can help troubleshoot any potential issues. This can be particularly important when it comes to tasks like installing isolation valves or dealing with specific error codes.

The Importance of a Maintenance Schedule

Consistency is key when it comes to tankless water heater maintenance. Setting up a regular maintenance schedule can help prevent the build-up of minerals and sediment, ensuring your system operates efficiently. It can also help identify potential issues before they become serious, saving you money on repairs in the long run.
